TeleMessage, the Signal-esque app used by the Trump administration, has been hacked

• Hacker claims they broke into messaging service TeleMessage
• TeleMessage is a clone of Signal, a popular privacy-oriented chat app used by the likes of JD Vance
• Hacker stole some files from the platform, but no US government data was taken

TeleMessage, an instant communications app used by some US Government officials, has reportedly been hacked, with private messages stolen.

A report from 404 Media says a hacker broke into, and stole messages found on the platform, which were then shared with the publication, allowing it to confirm the authenticity of at least some parts of the stolen archives.

In May 2025, TeleMessage gained media attention after it was revealed that Mike Waltz, former US National Security Advisor, was using an unofficial version of Signal called "TM SGNL," created by TeleMessage.
